FIELD OF THE INVENTION

The present invention relates generally to methods of management and execution of electronic bill payments, electronic purchase payments, fund transfers, other value exchanges, and physical facility access control. More specifically, the present invention relates to methods of management and execution of financial transactions and access control using mobile communication devices and particularly devices incorporating barcode, Quick Response (QR) code, and near field communication (NFC) technologies.

BACKGROUND

Modern day commerce involves conducting financial transactions through many different channels using a variety of instruments. Payment transfer of physical currency has been the most common means when the transacting parties are located away from any banking facility. Other payment methods and systems have appeared over the years. Credit cards, debit cards, Internet online payment services such as PayPal™, and monetary value holding electronic devices and systems, such as the near field communication (NFC) enabled Octopus Card widely used in Hong Kong, China, are some of the examples. However, none of the existing payment methods and systems has achieved the same level of ubiquity and ease of use as cash. Each of these payment methods and systems requires its dedicated infrastructure and/or is limited to a few channels. Another shortcoming of existing payment methods and systems is that person-to-person transactions are either unfeasible or highly inconvenient.

Due to their low production and distribution costs, the use of barcodes, QR codes, NFC and other radio-frequency identification (RFID) devices has gained tremendous popularity in various commercial and industrial applications. With the recent rise of use of “smartphones” incorporating cameras and NFC technologies and capable of running a wide variety of application software, many individuals are finding themselves equipped with ready and portable barcode and QR code scanners and NFC interrogators/readers. The present invention takes advantage of these increasingly prevalent smartphones equipped with cameras and NFC interrogators/readers in the hands of consumers in conducting various mobile payment transactions, ticketing management, and access control applications.

Lastly, the new consumer user is asked to provide the answer to a qualifying question, such as a portion of a government issued identification number.

User Validation:

4. The central processing server sends a validation email to the email address provided by the new consumer user. 5. The newly created user account is validated by the new consumer user receiving and reading the validation email, and accessing a validation web hyperlink, which bears the new consumer user's personal identification data within, in the validation email. 6. The access action of the validation web hyperlink sends the new consumer user's personal identification data to the central processing server; and upon the receipt of this data, the validation of the newly created user account is completed, and the new consumer user is notified as such.

User Profile Management:

7. After the newly created user account is validated, the new consumer user can access his/her user account by accessing the central processing server user interface and signing in using his/her email address, mobile phone number, and password. 8. After signing into his/her user account, the new consumer user can enter and modify his/her user profile information including, but is not limited to, name, email address, residence address, business address, delivery address, and mobile phone number for being saved and associated with his/her user account.

Funding Source and Fund-Receiving Destination Management:

9. Within the user account signed-in session, the new consumer user can add, modify, and remove one or more funding source and fund-receiving destination associating with his/her user account. A funding source and a fund-receiving destination are for crediting to (recharging) and debiting from (withdrawing) respectively the virtual repository of monetary units of his/her user account. Direct crediting to and direct debiting from a funding source and a fund-receiving destination respectively in a transaction is also possible. For adding a funding source or a fund-receiving destination, the new consumer user can select a credit card, debit card, bank account, or other funding source type, enter the card number or account number, the card or account holder's name and billing address, applicable expiration date and verification code. 10. The central processing server creates an unverified funding source or fund-receiving destination with the information entered by the new consumer user. 11. Only a verified funding source or a fund-receiving destination can be used to recharge or withdraw the virtual repository of monetary units of the user account, or for direct crediting to or direct debiting from a transaction. The new consumer user can initiate the verification of the newly added funding source or fund-receiving destination within the user account signed-in session. 12. For credit card type funding source, a debit of small amount is made against the credit card with a reference identifier associated with the transaction, which is shown on the credit card account statement. The debited amount is credited to the virtual repository of monetary units of the new consumer user's user account. The funding source verification is completed upon the new consumer user retrieving the reference identifier and entering it in the central processing server user interface during a user account signed-in session. 13. For bank account type funding source and fund-receiving destination, two debits of two different amounts are made against the bank accounts, which can be shown on the bank account statement. The debited amounts are credited to the virtual repository of monetary units of the new consumer user's user account. The funding source verification is completed upon the new consumer user being notified of the two debits and entering them central processing server user interface during a user account signed-in session. 14. Within the user account signed-in session, the new consumer user can indicate to the central processing server to link the virtual repository of monetary units of her/her user account with one or more verified funding sources and/or verified fund-receiving destinations for transferring funds between the virtual repository of monetary units and the linked verified funding sources and/or verified fund-receiving destinations.

Device Pairing:

15. A mobile communication device equipped with a NFC interrogator and/or a camera or barcode scanner must be associated (paired) with the new consumer user's user account. Only one mobile communication device can be paired with a user account at any one time. If a user account is already paired with a mobile communication device, it must be unpaired before another mobile communication device is paired with the user account. 16. The new consumer user configures his/her mobile communication device to be able to access the central processing server user interface. In one exemplary embodiment, the new consumer user uses his/her mobile communication device to access a mobile application store, find, download, and install the secure mobile payment and access control mobile application, which is specifically designed to interact with the central processing server, in his/her mobile communication device.
